"I’ve seen on the camera the poor guy making multiple trips to self empty while in one room but it’s cut the hair buildup tenfold."
"With three they can just make it to a full week for emptying. ... Life changing."
"The roborock cleans the carpet so well I haven't seen or felt any litter anymore."

"I upgraded to a roomba with the self emptying thing and I love it."
"Now we have two good ones (iRobot) with the bin that they self empty into when they get full. ... Before we got the one with the bins, it would get full and need emptying before it finished a whole cycle. Now it goes and empties itself and then goes back to cleaning."
"The station's neat though, washes and dries the mop pad, empties itself. ... Basically no work for me."

"Same here the i3 is awesome. ... I bought a parts kit on amazon for super cheap and it has really come in handy. ... I replaced the roller, even though it didn't need it after 3-4 years of use. ... The brush up front I've had to replace twice."
"you can buy replacement parts for under $40ish dollars. ... I have replaced battery, brush attachment, stick attachment, etc. - they are amazing."
"Every part is easily replaced ... It's still robust and serviceable"

"Roomba i3 for around 5 years and still better than my new shark robot."
"Honestly hardware reliability is the only thing Roomba has going for them. ... I've owned numerous robot vacuums and every single one has failed after about a year except for this POS Roomba i3 that I literally HATE lol. ... I've frisbeed that POS across the room so many times and it just keeps running ... even the bearing on the end of the roller seized up and melted and I just ignore it and it keeps chugging along not knowing where it is half the time."

"My dreame l20 ultra clogs with pet hair. ... We have one golden retriever dog and it seems to not go back to the dock enough even on the highest setting to empty."
"It leaves behind a LOT. No matter which setting I use, turbo, clean genius, etc there is still stuff left on the floors. I replaced filter, cleaned all the filters (including the one by the dust bin) and it still just leaves stuff behind."

"What ever you do don’t buy any with only one multi surface roller/brush. ... I have to clean the brush daily. ... It leave a “roll” of dog hair at least one place a day. ... The much more powerful suction is not enough to compensate for not having two rollers. ... Yes that is what I mean. One roller doesn’t do nearly as well as the two did."
"It still tangles very often (semi daily) because hair gets caught on the edge of the roller."

7x00 0.5Have an i3 and it's been amazing
Biorix 0.5I bought a roomba i3 in 2020, and it's still working fine Every part is easily replaced, and there is lifetime support that I use once to replace the battery Although that was before it was bought by Amazon, I don't know if it's still the same
Oh! I didn't know It's still robust and serviceable, but yeah, parts might be hard to find soon
cars_not_stock 0.5Just got mine for 85$ a couple weeks ago. It was pretty beatup. But I cleaned it up, replaced rollers, filters, and tires. Also took apart the base and cleaned it up. The thing is a beast. I had a i3 for a while so maybe that why it feels like such an upgrade. U could tell they definitely went all out on it
chtochingo 0.5For vac only, especially on carpet the roomba i3 on Amazon in like new condition was $70 last week. It’s $100 now but worth keeping an eye on it for a really cheap vacuum only robot. Especially on carpet the roomba 2 roller vacs do really well.
100%. I got a roomba i3 for under $50 and it vacuums on carpet really well. The roller design matters a lot, can’t believe some higher end models still have a single roller. Even with the patent expiring they still cheap out.
Roomba i3 on Amazon like new for $60. The base station came very used and clogged, complained to Amazon and got a full refund without having to return it. Does pretty well for my upstairs carpet only.
cornbreadnclabber 0.5I have a roomba- and heavy shedding dogs. I still have to vacuum weekly but it keeps us from being knee deep in hair. Get robot vacuum that empties into its own base. Some days it just has to empty its self over and over and over (coat blowing season). You don’t want a vacuum you have to empty as it would defeat the purpose of it being a robot. I buy bootleg replacement parts: filters, brushes, vacuum bag for base off of amazon. (I’m in US) I have not had any trouble
i3- it’s an old one.
cvdh94 0.5I have the Roborock Qrevo Plus, and it has been amazing! I have light colored floors and a black Dane and black Cocker. The robot runs every night and every morning we have clean floors. I have a 8 month old baby who is crawling so am also on the floor a lot and I’m always amazed by how spotless they are! Mapping was quick and painless, and I hardly ever have to intervene or rescue it. I also have a iRobot i3 and it’s a night and day difference. App is easy to use, and we have had it for just about a year and have had no problems. Refill clean water and dump dirty mop water once a week. Obstacle avoidance seems to work pretty well too, no incidents yet!
DaedalusCS 0.5I owned iRobot i3 - worked fine, but only real sensor - was front bumper, so he was “dumb”. Best thing about iRobot is that you can replace every part without 3rd party help. I had it for several years, not a single problem whatsoever.
In case of i3 there was no problem with hair on the rollers. I cleaned hair from tips of the roller from time to time, but that was like 30sec cleanup. More hairs were collected in the front wheel, but it was removable and easily cleaned.
Fun_Plankton8541 0.5And that sux! They are too expensive ..ordered the flow hoping it gets better in the corners and vacuums better..and guess I'm spoiled old roombas that are like tanks and last a long rime..has 3 yr warranty and comes with some stuff..I would think of it came to Costco it would be about the same.. but surprised doesn't have soap dispensary.. but does have a bigger battery so hoping 🤞🤞.. weirdly I cried giving up the 3i but it kept getting stuck in places I don't have problems with the others..😪
himbobflash 0.5I agree, it’s a shitty vacuum. I’ve spent $500+ on a Roomba i3 and I would do it again just for the dog hair. It’s a dog hair sweeper and it does a damn good job at that.
MammothCancel6465 0.5I beta tested a shark and an update randomly disconnected it from the app and it would not connect again and their beta test support was useless in getting it reconnected. Tried blaming it on my mesh system. I went as far as to get a stand alone router/wifi from my internet provider and hook that up and try to connect it that way and still the same thing. The app would freeze once it found the robot, even after updates. I really liked how the vacuum worked up until then but I’d never buy one after that. My 600 series Roomba and i3 Roomba have never had Wi-Fi issues on any of our network iterations over the years. I ended up buying a Eufy over Black Friday.
